A Theory-independent Way of Unambiguous Detection of Wino-like particles at LHC

G. Calucci, R. Iengo

We propose to use the change of the energy lost by ionization, measured by silicon detectors, before and after the passage through a bulk of dense matter, for unambiguously detecti…

Lower bound for the ratio of charged wino tracks to charged lepton tracks at LHC

Giorgio Calucci, Roberto Iengo

By using kinematical arguments we derive a theorem for the ratio: [production cross-section of charged-neutral wino pairs plus anything else] over [production cross-section of char…

The one-loop and Sommerfeld electroweak corrections to the Wino dark matter annihilation

Andrzej Hryczuk, Roberto Iengo

We compute the present-day Wino dark matter annihilation cross-section including the one-loop radiative corrections together with the fully treated electroweak Sommerfeld effect. W…

Relic densities including Sommerfeld enhancements in the MSSM

Andrzej Hryczuk, Roberto Iengo, Piero Ullio

We have developed a general formalism to compute Sommerfeld enhancement (SE) factors for a multi-state system of fermions, in all possible spin configurations and with generic long…

A Simple UV-Completion of QED in 5D

Roberto Iengo, Marco Serone

We construct a Lifshitz-like version of five-dimensional (5D) QED which is UV - completed and reduces at low energies to ordinary 5D QED. The UV quantum behaviour of this theory is…

Renormalization group in Lifshitz-type theories

Roberto Iengo, Jorge G. Russo, Marco Serone

We study the one-loop renormalization and evolution of the couplings in scalar field theories of the Lifshitz type, i.e. with different scaling in space and time. These theories ar…
